Since citrus flowering is a key process in citriculture and its evaluation is often difficult due to the canopy structure and field sampling, the aim of this research was to give some directions regarding the evaluation of flowering in field-grown sweet orange plants. This study was conducted in a citrus orchard of sweet orange plants cv. ‘Valencia’ [Citrus sinensis (L.) Osbeck] grafted on ‘Cle...

Canopy gaps are one of the most important structural features of forest ecosystems, and studying of them can have useful results and implications for forest management. The aim of this study is investigation of characteristics and regeneration within canopy gaps in an intact beech stand in the Shastkalateh Experimental Forest of Hyrcanian region, north of Iran. All canopy gaps and related fores...

The study aimed to determine the impact of sound land use management to the runoff in Kabuntalan, Maguindanao in Tamontaka river basin. This was done through simulation and the comparison of the three land cover scenarios such as 2015 land cover, 2025 projected land cover and desired land use to determine its difference in terms of runoff. Hydrologic Engineering Center-Hydrologic Modeling Syste...

This study presents a methodology for derivation of fractional canopy cover, detection of main tree species, and extraction of forest stands using logistic regression, airborne remote sensing data and field samples. In a first step, canopy height models (CHMs) are generated using medium point density LiDAR DSM and DTM and a high-quality matching DSM. Then, fractional canopy covers are calculate...

Usually, fatigue tests on fibre-reinforced composites are performed in uni-axial tension/tension or tension/compression fatigue [1], providing the S-N data. Although bending fatigue tests are not widely accepted as a standard, they are used a lot for research purposes [2] and they do have some important advantages [3]. In case of three-point bending fatigue, the history of bending force versus ...

In recent decades, one of the challenges in sheet metal forming was production of two-step bending surfaces without mechanical tools and external force or by a combination of heat source and mechanical tools. Forming with a heat source such as laser beam has the potential for forming arbitrary 3D shapes such as two-step bending surfaces. In this paper a novel method for laser forming of complic...
